Defined in header `<cmath>`

float pow( float base, float exp );

double pow( double base, double exp );

long double pow( long double base, long double exp );

float pow( float base, int iexp );

double pow( double base, int iexp );

long double pow( long double base, int iexp );

Computes the base raised by power exp or iexp.

`base`	-	base as floating point value
`exp`	-	exponent as floating point value
`iexp`	-	exponent as integer value

base raised by power (exp or iexp).

Domain error occurs if base is 0 and exp is less than or equal to 0. NAN is returned in that case.

Domain error occurs if base is negative and exp is not an integer value. NAN is returned in that case.

Range error occurs if an overflow takes place. HUGEVAL is returned in that case.
